sAEE'r'Y DEVICE FOR WINDOWS.

To all whom it may concern Be it known that 1, lemon D. BEAUNE, acitizen of the United States, and a resident of Brooklyn, boroughofQueens, and State of New York, have invented certain new and usefulImprovements in Safety Devices for Windows, of which the following is aspecification.

The objects of this invention are to provide improved means for barringa window in order to prevent children or others from falling out of thesame when open; to provide such means wherein the bars may beremovedfromacross the window as the win-. dowis closed or left acrossthe window as desired to provide means on the window adapted to raise orlower the bars therewith; to operate said means to throw it into eitheroperative or idle position from an elevated position out of reach of achild; to permit the window .to be raised or lowered independent of thebars when desired; to secure simplicity of construction and operation,and to obtain otheradvantages and results as may be brought out in thefollowing description.

Referring to the accompanying drawings in which like numerals ofreference indicate the same parts throughout the several views, Figure 1is an elevation of a window to which my invention is applied, saidwindow being viewed from the side which is ordinarily exposed at theoutside of ahouse;

' Fig. 2 is an edge view of thesame; Fig. 3 is a view similar toFig. 1looking at the 111- side of the window, the lower sash of which ispartially raised together with a baryFig- 4 is an underneath view of thelower sash;

- Fig. 5 is a perspective view showing a certain for-k, track and rider,and Fig. 6 is a transverse cross-sectional view taken on line A.-1ofFig. 3. p

In the specific embodiment of the invention illustrated in saiddrawings, the reference numeral 1 indicates a window comprising theusual frame 2 and upper and lower sashes 3, 4 respectively, slidablymounted therein. As is usual in windows of this kind the upper sash 3 isshown overlapping upon the outside of the lower sash 4 so that the lowersash may be raised or the upper sash lowered to open the window. Thepresent invention contemplates a means barring the window opening whenthe-- Specification of Letters Patent.

sash is opened and it will be obvious from the following descriptionthat the invention may be applied to either upper or lower sash.

The present disclosure illustrates the in,- vention arranged moreparticularly to bar the lower portion of the window and to this end avertical slideway is provided at each side of the window. Obviously sucha slide way may be made in various manners butfor illustrative purposes.guide strips 5, 5 are arranged vertically, one on. either side of thewindow and spaced from the frame by inwardly bent ends 6, 6 which arebent again toward each other to form portions 7, 7 parallel to the bodyportion of the strips adapted to bebolted or otherwise secured to theframe. As shown in the drawings, the strips 5, 5 are positionedsubstantially at the side edges of the sashes and extend from the windowsill upwardly above the top of the lower sash. A housing 8 between thewindow frame and each strip 5 is narrow enough to leave a verticalslot 9between its ing the slideway.

Positioned transversely across the window are a plurality of bars 10,one above the other, extending at their ends throughthe slots 9 andconnected thereat bv flexible members such asthe chains 11 whereby asthe top one is raised the other bars will follow successively with aspace left between dependent upon the extent of chain left between thebars. Obviously the same length of chain should be provided betweenboth.

ends of the bars so that they will be raised evenly Upward mov ment ofthe bars is limited in any suitable maner, so as to pre:

vent the lowest movable bar from being raised so faras to allow apersons body to pass thereunder. To this end a bar 12 is preferablysecured fast with respect to the strips 5 at their lower ends from whichthe lowestmovable bar 10 has limited movement upward. 7 e At each sideof the lower sash is cut a vertical slot 1-3 inthe portions of theframeforming the slideways for the lower sash of the window, said slotaffording an opening through which a lifting member upon the window mayproject through the frame and draw upon a flexible member 1 connectedPatented Mar.

window is opened. In carrying out the detailed construction foreffecting this result,

suitable sleeves 15, 15 are provided at the underside of the lower sashextending longitudinally of the lower reach and adjacentthe endsthereof. Vithin these sleeves are slidably mounted the stem portions 16of forks 17 said forks having bifurcated ends or prongs 19 extendingthrough the same upn opposite sides of a vertical way or track 19.Slidably mounted upon said track is a rider 2O transversely of the trackand transversely of the prongs, so thatthe prongs may underlie the saidrider on opposite sides of the track so as to engage the same evenly andraise it without tilting. To said rider is connected the flexible member14 which extends below the window sill making substantially a quarterturn around a pulley 21 then outward to a pulley 22 turning upward uponthe outside of the window frame between the same and the bars 10 to apulley 23 at the top of the vertical strip 5 over which said flexiblemember turns downward again and is connected at its lower end to thebars. As shown in the drawings said flexible member 14 is a cord or ropeand is connected to the chain 11 by a hook 24:. By this arrangement ofthe pulleys and the flexible member, as the window is raised with theprongs 18 of the fork 17 underlying the rider 20 the bars 12 will beraised also.

Means are preferably provided for retaining the bars in their raisedposition and allow the window to be lowered without lowering the bars.To this end a spring catch 25 of any suitable construction is positionedso that the latch 26 thereof is in the path of the bars 10 and at aproper height so as to underlie the top'one of said bars when at itsuppermost position. Preferably theunderside of said latch is beveled sothat raising the bar presses the latch in as the bar passes after whichthe latch springs outward again underneath the bar. From the inner endof'the latch extending toward the window frame is a connecting member 27which'may be drawn upon to retract the latch and release the bar so thatit may be lowered. Connected to the inner end of this member is one arm28 of a swinging member 29, the other arm 2300f which is inclined andadapted to be engaged and swung by the projecting prongs 18 of the fork16.

In order to retain the bars in their raised position across the windowand allow the window to be raised or lowered at will without affectingthe bars, the swinging member 29' is in a plane further from the side ofthe window sash than the plane of the rider 20, so that the fork may becaused to underlie and raise the rider. but not extended far enough toengage and swing the member 29. When it is desired to lower the bars thefork may be extended further so as to engage the member 29 and releasethe latch 26 so that as the window is lowered the bars will also belowered.

F or operating both forks simultaneously to extend or retract them alever 31 is pivoted to the side rail of the lower sash preferably uponits outer side and projects upwardly between the sashes above the lowerone, said lever providing a handle at its upper end above the lowersash. Said lever is fulcrumed as at 32 intermediate of its ends and atits lower end is connected with the stem portion of the fork at thatside of the window. Obviously, therefore, by swinging the lever, thefork 16 connected thereto may be extended or retracted as desired, andin order to extend and retract the other fork simultaneously therewith,the following means are provided.

Extensions 83 upon the inner ends of the fork stems are shown arrangedin a horizrntal plane adjacent the outer and inner longitudinal edges ofthe underside of the sash. Said extensions are separated from each otherlaterally and overlap longitudinally and provide each a plurality ofteeth 3% at their facing sides adjacent the ends. A pinion 35 in meshwith the teeth 34 on both extensions is pivoted to the sash between saidextensions. In operation, as the one fork is retracted, for instance,the pinion 35 in mesh with the teeth 34 of the extension of said fork isrotated and thereby causes the other fork to be drawn inward an eo ualamount. Obviously the distance .which the forks project beyond the sashis are extended as far as they will go and will underlie and raise therider 20 and bars 10 and when raised sufficiently will also engage theswinging member 29 to retract the latch 26 so as the sash is loweredagain the bars will also lower. Between the two extreme positions thelever' may be positioned at an intermediate position so that the forkswill be partially extended and underlie the rider to raise it and thebars, but not sufficiently extended to engage the swinging member 29.Consequently the sash may be raised its full extent and the upper bar 10will be engaged and held by the latch 26 allowing the sash to be raisedand lowered at will without affecting the bars. When it is desired torelease and lower the bars, the lever is swung to its extreme positionto extend the forks their full amount and the sash raised to trip thecatch and then lowered, taking the bars with it.

Obviously detail modifications andjchanges may be made in manufacturing-my improved safety device without departing from the spirit and scopeof the invention, and I do not wish to be understood as limiting myselfexcept as required byvthe following claims when construed in the lightof the prior art.

Having thus described the invention, what I claim is 1'. In a window,the combination with a sash adapted to be raised and lowered, aplurality of slidable bars adapted to be lowered in idle position orraised to extend across and bar the window opening, means for raisingthe bars as the window sash is raised, and releasable means forretaining said bars in raised position when the sash is again lowered.
